Then, if the inner cylinder 6, a superconductive coil 1, and the outer cylinder 7 have respective thermal contractibilities of alpha1, alpha2, and alpha3, they are selected to have the relation alpha1<alpha2<alpha3. As an example, when the superconductive coil 1 is composed of steel mainly, a SUS material is used for the inner cylinder 6, aluminum for the outer cylinder 7. Thus, because residual compressive stress by the inner-outer cylinders in the helium container, or a bobbin, or a supporting cylinder can be given to the superconductive coil, together with bobbin-side rigidity being enhanced, while the coil being cooled, the stress of the coil during excitation can be lowered, and besides capable of enhancing the cooling efficiency.

IPC: H04N1/32
Filed: 1986-06-25
Abstract: PURPOSE:To enable an operator at a facsimile equipment on the transmission side to instantaneously judge the status of a facsimile equipment on the opposite side by constituting the titled system so that the reception side monitors the function of its own respective operating parts, reports the result of the monitoring, and transmits the reception-unable factor included in the monitoring result through a line at a time when a call comes in. CONSTITUTION:If there is an incoming call, the reception side checks the presence/absence of information regarding the reception unable factor of an operating part supplied from a communication control part 10; if this information is not registered, a normal reception is executed. On the other hand, if this unable function factor information is registered, an NSF (non standard frame) signal including an unable factor information is transmitted. Thereafter, the reception side monitors the reception of a DCN(disconnection) signal from the transmission side, and at the time of receiving it, the line is released. As a result, the operator at the facsimile equipment on the transmission side can immediately judge the status of the facsimile equipment on the opposite side.
